You are driving in your car along a country road at a speed of 27.0m/s. As you come over a crest of a hill, you notice a farm tractor 25.0m ahead of you on the road, moving in the same direction as you at a speed of 10.0m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 7.00m/s^2. Will you hit the tractor before you stop? How far will you travel before you collide with the tractor? If you stop, how far is the tractor in front of you when you finally stop?
